I ran into this same problem today and wrote up this quick plugin that
accepts a boolean or function:
$.fn.extend({
showIf: function(fn)
{
var result;
switch (typeof fn) {
case 'function':
result = fn.call(this);
break;
default:
result = fn;
}
if (result) {
$(this.show());
} else {
Oops, fixed a typo:
$.fn.extend({
showIf: function(fn)
{
var result;
switch (typeof fn) {
case 'function':
result = fn.call(this);
break;
default:
result = fn;
}
if (result) {
$(this).show();
} else {
$(this).hide();
}
return $(this);
}
});

Since jQuery is about reducing and chaining, wouldn't it be nice if I
could write it like this:
How about something like (although i admit the function name could
use some thinking, heh)
(function($) {
$.fn.showorhide = function(bool) {
if (bool) {
$(this).show();
}
else {
$(this).hide();
}

Not sure if toggle(cond) is the best choice, though. It's already

overloaded as it is, and it can already take a string or numeric

Hmm, I actually checked the docs for that because that would make
.toggle an unsuitable overloader. The docs said toggle doesn't take

Hmmm, indeed. :) Not so
